Why ED-2 and not just ED? Are they the same as the ED ones for sale at Andrews? (they look the same).
They are rebadged Orion Epic ED (
http://www.scsastro.co.uk/it040022.htm), and to be honest, the ones I tried from Andrews weren't any better than my (cheaper) GSO plossls.
I found the 20mm eyerelief to be a bit much, and it was difficult to find a comfortable position for my eye - a lot of blackouts and kidney beaning. I also experienced a lot of internal reflections on bright stars.
HTH.
